Abstract

A towel dispenser includes a housing for receiving toweling. The housing includes a main body; a loading door that is configured to rotate relative to the main body between a closed position and an open position; and a guide system that includes a first roller attached to the main body and a second roller attached to the loading door. The towel dispenser can be mounted to an underside of a cabinet. In an aspect, the towel dispenser includes a motor and a transmission for feeding the toweling outside of the housing during dispensing of a towel, and an associated sensor. The motor is mechanically connected to the first roller by a transmission, and the second roller is connectable to the motor via the transmission.
